The O3b satellites orbit at 5,000 miles (8,047 km), more than four times closer to Earth than geostationary satellites, reducing the amount of time it takes for a signal to bounce between the spacecraft and Earth. The satellites in equatorial orbit can reach customers between 45 degrees north and south latitude. O3b Networks is now beaming Internet connectivity to service providers and telecom operators in Africa and the Pacific islands, reaching customers in South Sudan, Madagascar, the Democratic Republic of Congo, East Timor, Samoa and Nauru. O3b receivers are also installed on three Royal Caribbean cruise ships to provide passengers with high-speed Internet. The energy and government markets are also key business areas for O3b.
